SPECIFICATION forming part of Letters Patent No. 352,849, dated November16, 1886.

Application filed September 15, 1884. Serial No. 143,103. (No model.)

To all whom it may concern..-

Be it known that I, J OHN A. BALL, of Grass Valley, county of Nevada,State of California, have invented an Improvement in Plows, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts.

This invention relates to that class of plows known as reversible, andhas for its object the production of a reversible plow in which themold-board is made concaved and so piv-' oted as to be readily turned,so that its'concaved side will occupy a like position at either side ofthe beam at will, thesaid mold-board having attached to or forming apart of it a lay or share which is double pointed. The mold-board hereinshown is mounted to turn on a vertical pivot, and I have providedalocking device, which, when moved to release the mold-board, the plowbeing moved forward in the land, will be automatically shifted toreverse the throwing of the sod, and the action will be the same, nomatter whether the moldboard is at the right or at the left hand sideofthe beam.

Figure l in side elevation represents a plow embodying my invention;Fig. 2, a top or plan view of Fig. 1, the dotted line showing themold-board reversed. Fig. 3 is a section of Fig. l on the dotted linearm. Fig. 4 is a top View of the mold-board and its attached lay orshare. Fig. 5 is a horizontal section of the mold-board just above thelower guide-eye; and Fig. 6 is a section of Fig. on the line a." so.

The beam A and the handles B are and may be of any usual construction.The beam has bolted to its under side a suitable bearing, 0.

A bolt, D, is entered, as shown, from below,

up through a shoe, E, thence through the eyes upper and lower edges, andat the center of its length, and at or near its ends the said moldboardhas two other eyes, 6 7 ,which form part of the mold-board lockingdevice, to be de-' I f r.

FFICE. 7

full lines is supposed to be ready to cut and 7 turn a-right-handfurrow, but by turning the mold-board and its attached parts into thedotted-line position the furrow will be turned to the left, whichprovision it is obvious will enable the furrows to be laid in the samegeneral direction in the movement of the plow back and forth. I

To hold the mold-board in place I have provided a locking device (shownas a hand-lever, H,) pivoted at 10 on an ear of the bearing G, the saidhandle-lever having suitable prongs, h, one for each of the eyes 6 7 ofthe moldboard. A

In Figs. 1 and 2 the eye 7 is entered to hold the mold-board, as-in fulllines. To reverse the mold-board it is only necessary to lift thehand-lever H and remove the prong h from the eye engaged by it, andthereafter any forward movement of the plow, accompanied by a slightside tip toward the land side will, through the pressure of the landagainst the then forwardpoint, cause the mold-board to turn .on itsverticalv pivot, thus reversing the latter, and properly reversed thehandle will be dropped to enable the prong h next the then rear end ofthe mold-board to enter the eye nearest it, to thus lock the mold-boardin place until it is again desired to reverse the same.

The shoe E has substantially straight sides, and is of such width thatone or the other side may follow in the line of and form a practicalcontinuation of the landside from the point of the plow.

It will be noticed that the point of the lay" or share of my improvedmold-board is so shaped and constructed as to always occupy a positionat one side of the center of the beam, to thus equalize the draft.

I claim- I 1. The plow-beam A and its attached bearing 0, combined withthe shoe E, having a its center which encircle the sleeve and eyes 6 and7, as described, and the hand'lever pivoted to the said bearing andprovided with the prongs h, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
